To all whom it may concern:

Be it known that I, MAURICE HOFHEIMER, of the city of Baltimore, in theState of Maryland, have invented certain new and useful Improvements inClosures for Bottles, Jars, &c.; and I do hereby declare that thefollowing specification, taken in connection with the drawings furnishedand forming a part thereof, is a clear, true, and complete descriptionof the several features of my invention.

M said closures pertain to the class recognize as inside or throatsealing devices, as ished from the outside, or cap forms.

While effective as to the exclusion of air and the retention of liquids,my closures are not intended for, or capable of, resisting such highinternal gaseous pressures as are incident to the use of certain wellknown throat sealin devices.

Alt ough embodiments of one or more of the features of my invention arewidely applicable to various uses, and regardless of ordinary variationsin the contour of the throats of jars or bottles, their prime value willaccrue in connection with the marketing of natural waters in such largebottles as are usually employed, and also in the bottled milk tradewithspecial reference to sterilized products, involvlng the use of quitewide mouthed jars or bottles, and requiring in their closures apractically total exclusion of air, a reliable retention of contents,and a capacity to be readily opened.

For securing the stated. results certain conditions are imperative, andthese are provided for in my closures. in their simplest form, but formeeting many contin encies, the use of my closures embodying al of theseveralxfeatures of my invention may be relied upon.

Considered structurally, my closures in their most complete form arenovel in that they have an n wardly extended central cir-' cular bosswhic is enlarged at its top; and also have an upwardly extended annularflange which is provided with an inwardly turned or beaded edge;-also,there is between the bpss and the flange an annular recess or space, notonly for the reception of an annular tool for setting the closure in ajar or bottle, but also for the reception of the operating tip of alever opener for removing the closure.

To more particularly describe my invention, I will refer to the drawingsin which,

Figures 1, 2 and 3, respectively, illustrate one of my novel closures inits most complete form, in top view, in central vertical section, and asorganized with a water Lottle, and, with a lever opener indicated inposition for service. Figs. 4 and 5 illustrate a simpler form,respectively in top view and in central vertical section, and in whichthe edge of the flange is plain. Figs. 6, 7 and 8 illustrate my closure1n its simplest form, respectively in top view, central verticalsection, and as organized with a common form of milk jar. Fig. 9illustates in section, one of my closures, a water-bottle head and ahand-setting-tool for seating the closure for service.

My closures are composed of any suitable material ca able of beingworked into proper contact wit glass, but ductile sheet metal is welladapted to the purpose, referably aluminium, or quite light tin, and

they are molded into form or struck up by means of The closures A, A andA differ only as totheir embodiment of the features of my invention. Asin Fi s. 1, 2 and 3, all have an upwardly extended and an upwardlyextended annular flange b, terminating at its top in a circumferentialedge b and the coincident surfaces of the flange and boss are separatedby a properly proportioned annular space 0. These features areessential, and are often relied upon by me for assuring the main objectsof my invention. The boss a, being central, and upwardly extended, hastwo functions: mainly, it afiords an exterior annular surface forreliable contact by the tip of a lever opener, partly overlying theflange, as indicated in F i 3, that closure being organized with a botte B, so that in the act of o ening it may be lifted free from its seat,or t e side opposite the opener may be swung upwardly as indicated indotted lines; secondly, the

interior recessed portion of the boss, serves central circular boss a,

to divert from the junction of metal and glass, the impact of liquidwhen filled bottles and jars are in transit by wagon or rail andsubjected to violent rocking movement, because when the eontents aredashed sidewise and upwardly against the closure, they dash into theboss and then takings, ward direction, prevent undue impact at theclosure joint, resulting in-a minimum tendency to leakage. The annularrecess or space c has also two functions of equal imporlance, first, inaffording access .for an annular setting tool (asindicated in Fig. 9)which, when properly manipulated, bears against the flange and forcesitsouter surface into close engaging contact with the coincident glasssurface of the throat of the jar or bottle; and secondly, said space. or

recess 0 afi'ords free access to an opener, as

hereinbefore indicated.

In some cases the surfaces of bottle throats are ground, so that aneffective ongaging contact therewith is attained with a plain edgedflange as shown in Figs. 4 and 5, but for use with unground surfaces Ideem it wise, as a precautionary measure, to provide the circumferentialedge or top of the flan e with an inwardly turned or reinforced e ge asat 1), Figs. 1, 2, 3 and 9, there being a slight space between the metalsurfaces so that the setting tool, in forcibly. engaging with the turnedmetal, can safely drive the outer adjacent portion of the flange into anintimate contact with the nor mal glass surface, which is, of course,more or less irregular, in its contour, as compared with a groundsurface whether the circumferential edge I) or top of the flange be of asingle thickness of metal or reinforced,.it is susceptible of beingworked into close and effective sealing contact with the lass regardlessof the usual variations incldent to glass blowing and molding.

In such uses as may require a specially firm setting.of the closure, andinvolving corres ondingly greater force in opening, it is o importanceto provide the boss'with an abutment (for contact with or by an opener)more reliable than is afforded by the plain annular exterior surface,and for meeting such contingency, I provide the top of the boss with aperipheral enlargement 0/, thus securing an effective overhangingshoulder.

"Referring now specially to Figs. 4 and ,5,

it will be seen that the closure A is provided with the boss aand itsenlarged top or shoulder a and that it' has the annular space, or

recess 0. .v

In Figs. 6 and 7, the closure A. is in its simplest form, embodying theessentialfeatures hereinbefore referred to, 'i. e.-, the

vertically extended central'boss a, the-upwardly extended flange b, andthe double -functional annular space or recess 0.

down- New referring. to the bottle heads and throats of Figs. 3 and 9,it is to'be understood that they illustrate an ordinary form of waterbottle having a throat surface slightly inclined inwardlyi'rom the top,enabling an effective seating of the closure as indicated.

Should the throat be ground, a plain flange can be relied upon, but ashereinbeforc stated, the turned edge flange is better adapted for use inan unground throat, the setting tool (1 in either case requiring adownward thrust upon the bottom of the annular recess, with or without aslight rotative a slight gyratory movement of the setting tool whilesubjected to the thrusting action required as with the water. bottle.

The setting tool C should have a central recess and an appropriatelydimensioned annular working face adapted. to snugly enter-the recess orspace 0 of the closure, and

slightly tapered at the outer surface; it may be-composed of hard woodor of metal; it may or may not be vertically slitted to prowhich case aslight inward yield will be afforded, and hence its normal diameter maybe slightly greater than when not so' slitted, and the tool in eitherform should be slightly rotated in the act of setting a closure, and inclosing jars it should also be sli htly gyrated, as liereinbeforeindicated. hould it be found desirable to providea special setting toolfor milk jar service, well known expanding devices may be embodiedtherein for facilitating the operation.

I am aware from actual tests that if the outside of the flange andadjacent thereto be ,thinly coated with an odorless varnish, orparaffin, or even very thin paper, a specially tight joint will besecured.

Having thus described my invention, I

claim as new and desire to secure by Letters,

Patent,

1. A bottle closure for inside or throat sealing, having anupwardlyextended ee'n'-;

tral circular boss, peripherally enlarged-atits top, and an upwardlyextended annular flange provided at its topwith anedge turned inwardlyupon itself, substantially as and for the purposes specified.

2. A bottle closure for inside or throat seali having an upwardlyextended circular ange, and an upwardly extended ir-J 100 vide a seriesof sections as indicated, in I having a throat of suitable contour, ofan cular boss eripherally enlarged at its top, substantial y asdescribed.

3. A bottle closure for inside or throat sealing, having an n wardlyextended central circular boss, an an upwardly extended annular flangeterminating at its top in a circumferential edge, and with thecoincident surfaces of the flange and boss se arated by an annularrecess or space affor 'n access for an annular setting tool, and aisofree access for the tip of an opener o erating as a lever when overlyithe e ge of the flange, substantially as escribed.

4. A bottle closure for inside or throat sealing, havi anupwardlyextended circular oss, an an upwardly extended annular flange providedat its top with an inwardly and downwardly turned reinforced edge,substantially as described.

5. The combination with a ar or bottle inside or throat closure providedwith a circular upwardly extended central boss, and an upwardly extendedannular flange having its circumferential edge and outer surface intightly closing contact with thecoincident surface of the bottle andappropriately located with relation to the circular surface of the boss,to afford a recess or space for the free rece tion of a setting tool andfor receiving t e ti of a lever opener when engaged with t e side of theboss with its shank overlying the flange and the lip of the bottle,substantially as described.

In testimony whereof, I have hereunto set my hand in presence of twosubscribing witnesses.
